What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

CWC G10 Fatboy-80 Quartz Re-Issue Watch

Owners widely praise the CWC G10 Fatboy-80 Quartz Re-Issue Watch for its 36mm size and comfortable, "chunky" wearability, with one owner calling it their "perfect watch." The bead-blasted stainless steel case, fixed spring bars, and acrylic crystal that scratches but buffs out are noted features. Some enthusiasts point out the dial's "T" marking alongside Super-LumiNova as a detail difference from originals, and one owner found the reissue's crystal magnified the dial more. The 50m water resistance is considered sufficient for its field watch purpose. On balance, owners rate the CWC G10 Fatboy-80 Quartz Re-Issue Watch highly for its comfortable wearability and distinct dial at its price point.

Seestern S450 Ocean Star

Owners widely praise the Seestern S450 Ocean Star's Yachtmaster-style case and flawless bracelet finishing, with one owner noting the ST2130 movement keeps good time. The bezel action is described as having individual notches but feeling like a friction bezel, while another owner flags the bezel and crown action as smooth with perfect alignment. Lume is a point of contention, with one source describing it as a nice cool blue with ice-white application, while others note it as weak or not matching Prospex standards, despite using BGW-9. The watch is considered a "big boy" ideal for larger wrists (19cm+), potentially too large for 17cm wrists due to its size and non-tapering bracelet. Overall, owners rate the Seestern S450 Ocean Star highly for its build quality and finishing at the price point, despite some reservations about its size and lume intensity.
